Starting to map out where I want to do my shooting with my new .17 HMR. Miles and miles of BLM desert here.

So, to be absolutly safe, erring to the extreme towards safety, assuming I knew at what elevation the bullet would travel farthest, and I shoot it on a windless day at that angle, what is the farthest that that bullet could travel (which I assume is the point at which it contacts the ground, and beyond which there can be no danger from my weapion)?

Thanks.
